TextService

Computes the Vector2 dimensions (in pixels) that will be taken up with text when using the specified formatting parameters and size constraints.

Note, the fontSize parameter will not accept the Enum.FontSize Enum. Instead the integer size corresponding with the Enum.FontSize Enum should be used. This is not equal to the value of the Enum.FontSize Enum. For example, for Size11 font, the integer 11 should be used.

This function is a useful alternative to the TextLabel.TextBounds property of the TextLabel and TextButton objects. Using the TextLabel.TextBounds property to calculate the dimensions text requires is often impractical as it requires a TextLabel object to be created.

With GetTextSize, the dimensions required by a particular text string in a particular TextLabel or TextButton can be calculated before any object is created or text property set.

Developers are recommended to add a pixel of padding to the result to ensure no text is cut off.

This method is limited to only fonts that are listed in Enum.Font. To get access to more fonts, you can use TextService:GetTextBoundsAsync() instead.

Chat translation is not supported in legacy chat. This method is no longer supported and should not be used. All calls return an empty object. Translating chat messages is only available via TextChatService.

The FilterStringAsync function filters a string being received from a user, using the TextService, and returns a TextFilterResult which can be used to distribute the correctly filtered text accordingly.

Usage

This method should be called once each time a user submits a message. Do not cache the results of this function and re-use them for separate messages. If a user submits the same text multiple times this method must be called again each time the message is sent. If the results are cached and reused spam detection and many forms of context-aware filtering will be broken and potentially put user safety at risk. Games that improperly use cached results may face moderation.

However, it is encouraged to keep these result objects to display the same message to users who join the server later. For example: this can be used to safely and efficiently implement a server chat log that always uses the least restrictive filtering for users who join later, or for efficiently displaying text like a pet name to a user who joins the game after the pet was first spawned and name filtered.

The optional Enum.TextFilterContext parameter will not impact the filtered result of the query. This value will be used to improve Roblox's text filtering.

Private text is anything that is seen only by specific players, rather than every player. For example, if the chat is seen by a single player, or by a selected group of players, then the chat is considered private. Chat for teams or chat that is potentially visible to a wider group, such as the server, is considered public. If you are unsure what your text qualifies as, leave the optional field blank.

Note:

• This method always yields to make a text filtering service call
• This method may throw if there is a service error that can not be resolved. If this function throws an error please do not retry the request; this method implements its own retry logic internally. If this method fails do not display the text to any user.
• This method currently throws if fromUserId is not online on the current server. We plan to support users who are offline or on a different server in the future.

Returns a table containing the name and faces of a font family.

The returned table is structured like this:

type FaceInfo = {
  Name: string, -- Examples: "Regular", "Book", "Italic", "Thin Italic"
  Weight: Enum.FontWeight,
  Style: Enum.FontStyle, -- Either Normal or Italic
}

type FamilyInfo = {
  Name: string, -- Examples: "Source Sans Pro", "Grenze Gotisch"
  Faces: {FaceInfo} -- There's always at least 1 but there can be up to 18.
}

If the font family has already been loaded by a previous call to GetFamilyInfoAsync, ContentProvider:PreloadAsync(), or a text object with the TextLabel.FontFace property set, then the method returns without yielding.

Errors

This method can fail because of network errors. You should always wrap it in a pcall for error handling.

Throws an error in these scenarios:

• The passed family is an empty string.
• Downloading the family failed.
• The asset ID is invalid or points to an asset that doesn't exist.

local TextService = game:GetService("TextService")

local familyToCheck = "rbxasset://fonts/families/Arial.json"

-- This is a yield function which may take up to a few seconds to download the font.
local info = TextService:GetFamilyInfoAsync(familyToCheck)

print("Name of the font:", info.Name)
print("Faces:")
for _, face in info.Faces do
  print("--------")
  print("Name:", face.Name)
  print("Weight:", face.Weight.Name)
  print("Style:", face.Style.Name)
end

This method is similar to TextService:GetTextSize(), but uses the Font object instead of Enum.Font, which has access to more fonts.

Used to measure how big some text will be given a set of properties like the string, size, and font.

This is a yield function because some fonts may need to be loaded in order to measure them. If the font is already loaded, then it will not yield. ContentProvider:PreloadAsync() can be used to make sure a font is loaded.

Errors

This method can fail because of network errors. You should always wrap it in a pcall for error handling.

Throws an error in these scenarios:

• The GetTextBoundsParams.Font has a blank family.
• The params argument was nil.
• The font family or font face failed to download.
